Velux Standard Slate Flashing Including Bdx Insulation Collar to Suit MK08 Roof Window 780 x 1398mm

The VELUX Pro+ flashing set is designed to ensure a perfect installation with extra insulation. The VELUX Pro+ flashing set comes with an easy-to-fit underfelt collar that includes an integrated drainage gutter. The underfelt collar creates a tight seal between the roof window, battens and the roofing underfelt. The drainage gutter gives you extra security by draining away any water that gets through to the roofing underfelt safely and effectively from the top of the roof window. The VELUX Pro+ flashing set also includes an insulation frame that insulates the gap between the roof window and the roof construction. This reduces heat loss and eliminates cold bridges. Whatever your VELUX window size or type, the flashing set fits perfectly and provides a durable and weathertight seal that can stand the test of time. Everything you need in one box for a weathertight installation – with added insulation. Ensure a watertight seal between the roof window and the roofing underfelt with the VELUX underfelt collar that leads water away from the roof window installation. Reduce heat loss and eliminate cold bridges with the VELUX insulation frame. The combination of rigid and flexible foam creates a tight seal between the roof window and the roof construction and makes it easy to install.
